I bought my flashmaster 3 years ago, and its been hanging off my neck banging into my tripod for most of that time. I've been photographing people swimming in lakes and ponds, and have accidentally dipped it into the water 3 times. It still works fine. A friend of mine came over to my house to take my portrait on my outdoor patio. He left his L-358 on the ground, and two weeks later I discovered it underneath some leaves. I feared the worst but turned it on and it still works flawlessly. It had been a rainy 2 weeks. The battery lasts between 6 months and a year and costs about $6. In college I took a 16mm film class and shot perfectly exposed slowmotion film with a 40 year old bolex and my sekonic set to the motion picture setting. I am not saying we should abuse our equipment but something this rugged deserves praise. If IPODs were built this tough Apple would be out of business. They expect the customer to shell out for a new one every 2-3 years.
Anyways thanks sekonic
